摘要:

减摇鳍是解决船舶横摇的有效办法之一,可提升邮轮的舒适性.该装置一般由一对或两对可伸缩的鳍组成,对称地安装在船舶的两侧舭部,通过控制算法依靠鳍的水动力升力提供运动阻尼.然而,不同航速和不同攻角下减摇鳍与船舶的耦合分析还较少,尤其是船体流场对鳍阻力的影响尚缺乏研究.利用模型试验和数值分析方法研究某邮轮的阻力性能和鳍的运动影响,比较数值和模型试验结果,对减摇鳍引起的阻力和船鳍耦合运动进行研究,为减摇鳍的设计和选择、邮轮设计和性能预报提供了参考.

关键词: 减摇鳍, 模型试验, 邮轮, 不同攻角, 不同航速

Abstract:

Fin stabilizers represent an effective solution to address the roll motion of ships and improve the comfort of passengers on cruise ships. These devices typically comprise of one or two pairs of retractable fins, symmetrically mounted on either side of the ship, which utilize hydrodynamic lift to dampen motion through a control algorithm. However, coupling analysis of fin stabilizers and ships at various speeds and angles of attack remains limited, particularly with regard to the impact of the hull flow field on fin resistance. This paper investigates the drag performance and towing motion of a cruise ship using model tests and numerical analysis methods, and compares the results of the numerical and model tests. It also examines the drag resulting from fin stabilizers and the coupling motion of the ship, offering insight for the design and selection of fin stabilizers, cruise ship design, and performance prediction.

Key words: fin stabilizer, model test, resistance, cruise ship, different fin angles, different ship speed
